Product FAQs
5 answersWhat is the difference between this EPD breaker and a standard GFCI?
The CHB120EPD is an Equipment Protection Device (EPD) that trips at a 30mA ground fault threshold to protect machinery and heat tracing. Standard GFCI breakers trip at a 5mA threshold for personnel protection.
Which panelboards accept the CHB120EPD?
This bolt-on breaker is designed specifically for Eaton and Cutler-Hammer Type PB and PH panelboards, as well as compatible meter panels.
How is the neutral connected on this breaker?
It features a pigtail neutral wire that must be connected directly to the panelboard neutral bar to power the internal ground fault circuitry.
How much panel space does this breaker require?
As a 1-pole CHB frame breaker, it requires a single 3/4-inch space in the panelboard.
Can I use this to replace a standard CHB120 breaker?
Yes, it will fit in the same 3/4-inch space and bolt onto the same bus as a standard CHB120, but it provides added 30mA equipment ground fault protection and requires a dedicated neutral connection.
